Hey, it's not necessarily a bad thing to use your ipod touch too much.
Personally, because of the great screen, I've jury-rigged a nice webcam on top of my touch and instead of looking at things with my eyes, my touch does it for me, and I get to experience the world on my... its wonderful screen.
I'm in the process of adding a microphone so I can do away with ears. I just can't wait until they come up with a taste or smell sensing device, and don't get me started about using sonar to touch things. That's when the ipod touch will truly live up to its name and do away with all human senses.🙂
But mostly (and realisticly), I just hope I'm not spending too much time here thinking about getting my touch while building up the hype.
